Application filed September 27, 1917. Serial No. 193,541.

To all whom it may concern:

Be it known that I, FRED C. DENNIS, a citizen of the United States, residing at Blair, in the county of Jackson and State of Oklahoma, have invented certain new and useful Improvements in Automatic Gasolene-Dispensing Machines, of which the following is a specification.

This invention is an automatic gasolene machine and has for its principal object the production of a coin controlled mechanism which will dispense a predetermined amount of gasolene or other fuel to be received therefrom.

Another object of this invention is a production of an automatic gasolene machine wherein the coin inserted in the device will cause a valve to open for permittinggasolene to flow into a weighing tank and after a predetermined amount of gasolene passes into the tank, the flow of the gasolene into the tank will be stopped.

A further object of this invention is the production of an automatic gasolene machine wherein the coin control mechanism will automatically open a valve in the bottom of the weighing tank for permitting the gasolene to pass therefrom after the proper quantity of gasolene has been injected therei into.

A still further object of this invention is a production of an automatic gasolene machine wherein the coin controlled mechanism will be automatically reset for another operation after dispensing a predetermined amount of gasolene.

Viththese and other objects in view this invention consists of certain novel combinations, constructions, and arrangement of parts, as will be hereinafter fully described and claimed.

One practical form of construction and assembly will be described and is illustrated in the drawings, in which- Figure 1 is a central vertical section of the automatic gasolene machine.

Fig. 2 is a horizontal section taken on line 22 of Fig.1, looking in the direction of the arrows, portions of the machine being removed Fig. 3 is a section taken on the line 3-3 of Fig. 1 looking-in the direction of the arrows, portions of the machine not being shown. j

Fig. 4: is a' section taken on the line 4 1 of Fig. 1, looking in the direction of the ar rows and, i i

Flg. 5 is a vertical section taken on the line 55 of Fig. 1 looking in the direction of the arrows, portions of the device being shown in elevation.

Fig. is a fragmentary detail perspective v ew of a portion of the operating mechanism. 1

Referring to the drawings by numerals, it will be seen that the automatic gasolene machino comprises an outer casing 1 which of course may be of any suitable shape as illustrated in Figs. 2, 3 and 1, while the lower end of this casing 1 rests upon the base 2, being secured thereto by securing-means 3. The cover {lis secured, as shown at 5, upon the upper end of the casing 1, whereby access may be had to the interior of the machine, if desired. s

The supply pipe 6 projects through the base 2 and extends to a point. adjacent the top 1 as shown in Fig. 1. The upper end of the supply pipe 6 is provided with a goose neck 7, for purposes to be hereinafter set forth. The brackets 8 are provided with bases which are held in fixed position upon the casing l. The brackets 8 are provided with clamps 11 held by securingmeans 12 upon the supply pipe 6 for holding the same in a fixed position within the casing 1.

The dischar e funnel 13 has a nozzle 14 projectingthrough the casing as shown in Figs. 1 to at inclusive. Theclamping band 15 engages the funnel 13 and has its ends 16 secured to the casing l in any suitable manner and thereby holds the funnel 13 in a set position. Since the nozzle projects beyond the outer sideof the casing, it is obvious that a hose may be applied thereto for conveying the gasolene dispensed by the machine to a desired point.

The tank 18 is positioned above the funnel 13 and is slidably mounted upon the supply pipe 6 by the bracket 19, this bracket 19 being secured to the weighing tank 18 and being slidably mounted upon the supply pipe 6 by a loose clamp 20. The cover 21 is car- 'ried upon the upper end of the weighing tank and is provided with ears 22 pivotally secured as indicated at 23 to the beam 2 1.

shown at 28 to the beam 241. The weight 29 is slidably mounted upon the beam 20 and as a consequence constitutes a balance for the weighing tank 18. It should be understood that when the weighing tank 18 is empty the weight 20 will hold the weighing tank in its highest position. lVhen however the weighing tank 18 is filled, it will move to a lower position by suddenly overcoming the counter balancing effect of the weight 29. It will be noted that the neck 7 of the supply pipe 6 projects through the cover 21 of the weighing tank 18 and extends into this weighing tank as shown in Fig. 1.

\Vhen a customer desires a quantity 0 gasolene, he inserts a coin through the opening formed in the casing 1 and the coin guide 31 registering with this opening 30 directs the coin downwardly in an cdgewise manner, thus causing the coin to strike upon the trigger 32 positioned directly beneath the coin guide 31. carried below the guide 31 and constitutes a receiver for the coin after the same disengages the trigger 32. It will be noted that the pocket 33 has a slot 34: at one side thereof thus permitting the trigger 32 to project into the pocket 33. It should further be noted that the door 35 is hingedly secured as shown 36 to the casing 1 and constitutes a closure for the pocket 33. In order to prevent unauthorized access to this pocket there is provided any suitable form of a locking device as shown at 37.

The bracket 38 is fixedly secured as shown at 39 to the casing 1 and the depending portion 40 of the trigger 32 is pivotally secured thereto as shown at 41. In order to urge the trigger in one direction a coil spring 12 is connected at its ends to bracket 38 and the depending portion 40. The lower end of the depending portion 10 is provided with a head 43 for purposes to be hereinafter set forth. The, shaft 4 1 is rotatably mounted upon the bracket 4:5 while the primary weight L6 is fixed upon one end of the shaft 4 1. The head 43 'normally engages the weight l6 for holding the same in a set position as indicated in Fig. 1. When however, the trigger 32 is swung by a coil falling thereon it will swing the head away from the weight 16 for releasing the same. This primary weight 16 will then swing downwardly thereby allowing the valve cord "17 connected to the bar 18 carried by the weight 16 to become slack. This valve cord 47 passes around the pulley 19 carried upon a bracket 50 which is clamped upon the supply pipe 6, as indicated at 51. The valve cord 4:7 is then connected to a lever 52 eX- tending from the rotary valve 53 carried within the valve casing 5 1. This valve casing 5 1 is carried by the supply pipe 6, as shown in Fig. 1. The coil spring 55 is also connected. to the lever52 and is supported by the flange 56 of the bracket 57, which is fixedly mounted, as indicated at 58 within The coin pocket is the casing 1. It is therefore obvious that as the primary weight 16 swings downwardly and the valve cord l7 becomes slack the coil spring 55 will swing the lever 52 in one direction, thereby opening the valve 53 for permitting a free passage through the supply pipe 6. At this time, the gasolene will pass through this pipe and into the weighing tank 18. The weighing tank 18 is provided with a depending neck 59 which carries the sleeve 60. The ball valve (Si is provided with a stem 62 depending therefrom and extending through the neck 59 into the sleeve 60 as shown in Fig. 1. The operating link 63 is connected. to the stem 62 and the link 63 is normally urged downwardly at one end by the coil spring (a secured thereto and carried by the sleeve 60. In this way it is obvious that the ball valve may be held against accidental movement, while the weighing tank 18 is being filled. After the weighing tank 18 is nearly filled with gasolene flowing from the neck 7 the tank suddenly moves downwardly, thus swinging one end of the beam 24: upwardly. The end of the beam which is thus swung upwardly projects through the slotted bracket 65 fixedly secured, indicated at 66, to the casing 1 adjacent the upper end thereof. The flexible strand 67 is seen red to the last-mentioned end of the beam 24 and passes through the bar 4:8 mounted upon the primary weight 46 and carries the nut 68. Therefore, as the end of the beam 2e moves upwardly it will draw upon the last mentioned strand .67 and thus swingthe weight 46 upwardly, thus causing the weight to draw upon the valve cord 17 'ior swinging the lever 52 against the tension oi? the spring thereby closing the valve 53 and the How.

otgasolene into the weighing tank will be automatically shut olT.

Vhen the weight 16 is swung upwardly in the manner hereinbefore specified the finger 69 carried by the weight 46 will be swung into engagement with the tripping arm 70. This tripping arm 70 is pivotally supported as shown at 71 upon the bracket 57. This tripping arm 70 is also provided with a latch head 72 which is normally held in engagement with the auxiliary weight 7?, by the coil spring 74.

The auxiliary weight 73 is pivotally mounted upon the shaft 4% and is connected by the cord 75 to the bar d8 of the weight 46. This cord 75 passes over the pulley 76 mounted upon the bracket 38 and it is there fore obvious that when the primary weight &6 swings to a lower position it will draw the auxiliary weight upwardly as it is intended to have the primary weight weigh slightly more than the auxiliary weight. The bracket 77 is fixedly mounted upon the weight 73 and is provided with a slot 78 adjacent its lower end. The link 63 is pivotally supported by the bracket 79: carried within the casing 31 and this link projects through the slot78 inthe'bracket' 77. ,As

the auxiliary weight movesthe bracket 77 downwardly thebracket will swing the link 63, thereby causing the stem 62 :to lift the;

to be dispensed into the funnel 13 and be finally passed'from the casing 1. It should further be understood that as the weight swings downwardly the finger 80 will swing upwardly. The tightening cord 81 is attached to the finger 8O and'passes through the guide=eye 82. This tightening cord 81. is also provided with an eye 83 through which the valve cord 47 extends as shown in Fig. 1. It is therefore obvious that as the finger 80 is swung upwardly it will drawupon the tightening cord 81 to further tighten the cord 47 for positively holding the valve in a closed position.

The weight 29 on the beam 24: will move the tank 18 upwardly when sufiicient gasolene has been discharged from the tank so as to allow the weight 27.to counter-balance same. This will cause the flexible strand 67 to permit the primary weight 46 to then have a free engagement with the head 43. When another coin is inserted in the machine to cause the primary weight to again move downwardly, the cord 7 5 will immediately move the auxiliary weight 73 upwardly thereby causing the weight 73 to permit the ball valve to return to its seat for retaining the gasolene injected into the weighing tank for a predetermined time.

The operation of the machine may be repeated as often as coins are inserted into the coin slot. It will be seen by referring to the foregoing description that as one weight is lowered the other weight is raised. It will further be noted that as the primary weight is lowered the auxiliary weight is raised, and the valve operated by the auxiliary weight will be moved to a closed position, while the valve operated by the primary weight will be opened thereby permitting gasolene to be injected into the weighing tank and be held against displacement at the time this action is taking place. After the tank is filled, however, the primary weight will be finally raised to an elevated position for cutting off the flow of gasolene, and the auxiliary weight will be lowered for opening the valve in the bottom of the tank for permitting the gasolene measured thereby to be dispensed therefrom.

I From the foregoing description it will be obvious that a very eflicient self measuring machine has been provided, wherein after a coin has been inserted therein a proper quan tity of gasolene may be measured and then be dispensed although while the dispensing .iaction is taking place=th e supply of liquid fuel to the weighing tank will be cut off.

It is of course obviousthat'in many minor details-:changes may be made inatheconstruction of this inventiom'such for instance,:.as

the manner in whichthezvarious brackets are employed for supporting the differenttpiw oted elements-without departing from the spirit of the invention and for thisireason it is not intended to limit the construction of this self measuring machine to the specific form herein shown,.as it is intended to m- V clude all such forms of the device as properly come within the scope of claimed.
